Witness, the weekly party in Scotland's capital city of Edinburgh, is still going strong, and is celebrating this week with the release of its second free EP. Featuring a diverse group of new talent, the EP resides mostly in the 130-140 bpm range and is, unsurprisingly, engineered for the dancefloor. Atticus Jacks' "Potential" track is a particularly wound-up slice of energetic house which splits the difference between Addison Groove and Jacques Greene. A tight kick drum pattern and some offset cymbals intersect with a syncopated cowbell throughout the production—eventually, a thick bassline fills out the remaining frequencies and samples of a preacher pair with a smattering of resonant arpeggios to reach a very deserved climax. The rest of the Witness crew's EP can be downloaded for free, after the jump.
